Description

General description

Bis(trifluoromethane)sulfonimide (TFSI, Tf₂N) is utilized as anion species to form 1-ethyl-3-methylimidazolium molten salts. It undergoes acid-base complexation with rod-like poly(2,5-pyridine) to afford highly-ordered lamellar self-assemblies in the hydrated films.

Application

Bis(trifluoromethane)sulfonamide may be used in the following studies:

• As catalyst during the polymerization of octamethylcyclotetrasiloxane in the presence of hexamethyldisiloxane.
• As efficient catalyst in the synthesis of various non-reducing disaccharides, via ketopyranosylation of 2,3,4,6-tetra-O-benzyl-1-C-methyl-D-hexopyranoses.
• Starting material for preparing the N-fluoro derivative, a reactive fluorinating agent.
• As a component of solid polymer electrolytes.
